Good day , I have currently a 500Hz Collins filter and a 250Hz Yaesu filter installed in the main receiver of my FT 1000 MkV. I found that I use the 250Hz filter most of the time for weak dx on 160m,

Raoul, It's not just the filter that matters, its the filter skirt response too. I have 2 x 400Hz INRADS in my MkV (one in each IF) and another in the sub rx. IMO the INRAD 400's are a better option

For weak signal work with no strong signals capable of overloading RX stages, there is no advantage in installing 250 Hz at 8215 kHz IF. Operating comfort may be increased slightly by a narrow filter

My mistake, NOT is missing, should read as follows: Operating comfort may be increased slightly by a narrow filter, such as Inrad's 125 Hz at 455 kHz IF, or the built-in 60 Hz DSP APF. They will NOT

YES! As it happens, I recently completed a somewhat extensive series of measurements of filters in both my K3 and two FT1000MPs. Most are Inrad filters. They can be downloaded as a pdf with the follo

In my noisy suburban QTH, I find that the Inrad 125 Hz 455 KHz filter cascaded with the MK V's 60Hz DSP APF filter makes it easier for me to copy weak CW signals. I think (but I can't prove) that in
